Be it known that I, Jams G. BLUNT9 e of the United Stet-es, i'e'sitling et @ehenecterly, Schenectady @rmrity New 'frTm-k, e ieventeol a new and useful-Km pavement LetemtMotion Devices tor Locomotive Driving Boxes, xvi; oh the following is a specification, reference being had to the accompanying drawings, 1x1 which v Fig. l is plan, parity in section, showing the spplicationof my invention to the driviegs 1e boxes of a locomotive engine;

Fig. 2 is at front el'ex' ation thereof partly in section; Fig. 3 is at side elevation thereof;

and Fig. -1: is s detailed perspective of one o1? ie rockers.

My invention relates to devices fox controlling the lateral motion of tiriving boxes of locomotive engines and; thereby limiting the lateral movement of the drlving axles, and at the some time providing resistsnce to that movement to aid the locomotive in absoybing lateral shocks sml to sist it in passing around curves. E ly impro tlevice is so (tesigneol that the tetecel movement 01 one driving box is ttzmsmittec?- to the opposite frame, with the result thet resctiofxi the device the frame housing the opposing one; serves to exert Referring; to title d&tWlfilgS., in each side of the main frame 1 striving extes 2, ere journalist? in axle or driving toxes 3 WOYl ing in pedestets 1 in the frame 1 end {guttied wectges d shoes 1G1 joucnais 5.

As the lever 12 is connected to the opposite lever 12 through the spring resistance device 1% the movement of the upper end of one lever tends to move the other lever correspondingly, but such movement of the other lever is prevented since the projection 12 at the lower end bears against the frame. Hence compression of the springs 15 taltcs place which sets up a force tending to return to itsnormal position the box from which the movements just described initiated.

My invention is of particular advantage, since it does not require any particular construction of frame or driving box but may be applied -to driving boxes of the usual character. It has the further advantage that. in removing driving axles from the loco1notive no part of the mechanism requires removal or disturbance.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the feature shown and described, or portions thereof, but recognize that. various structural modifications are possible within the scope of the invention claimed.

What I claim is:

1. In a locomotive engine, the combination of frame; driving axle boxes mounted in said frame and capable of a limited lateral movement relative thereto; an axle rotating in said boxes; and mechanism supported by the frame comprising means for transmitting lateral movement of one box to bring pressure upon the portion of the trame housing the opposite box and of reacting against the first mentioned box to exert pressure to restore it to normal position.

2. In a. locomotive engine, the combination of a frame; driyingaxle boxes mounted in said frame and-capable of a limited lateral movementrelative thereto; a lateral resist; ance device; and a connection between said device and each driving bd x supported by the frame, said device comp rising means for transmitting movement oi:- one box to bring pressure upon the portion ol the frame housbox, said device also comprising means for exerting; pressure to restore the first mentioned box to normal position.

3. in a locomotive engine, the combination of av trame; driving axle boxes mounted in said frame and capable ol a limited lateral movement relative thereto; a lateral resist-- ance device, and levers pivoted upon the resistance device and the boxes, said lateral resistance device ings rigid with n wearer and said levers comprising means for transmitting lateral movement of one box \vhile forming a fulcrum a 'ainst the frame on the opposite side, and at the same time forming a resistance to lateral movement of either box independently of the other and constantly tending to move into normal position.

al In a locomotive engine, the COll'lbllldtlOll ot a trame; driving axle boxes mounted in said frame and capable of a limited lateral movement relative thereto; a lateral resist,- ance device; levers pivoted upon the frame and engaging the lateral resistance device and the boxes; said lateral resistance device and said levers comprising means for resisting the lateral movement of one box while forming a. fulcrum against the frame on the opposite side and constantly tending to move the box oflering resistance back into normal position; and means for limiting the outivard movement of the free ends of said levers.

In a locomotive engine, the combination of a frame; driving axle boxes mounted in said frame and capable of a. limited lateral movement relative thereto; levers pivoted upon said frame; and spring mechanism joining ends of said lovers, the opposite enc s of said levers having a bearing upon said frame, the lovers and spring mechanism comprising means for transmitting lateral mo" tion of either box in the form'ot pressure against the opposite frame and of reacting a gainst the said box to restore it to normal position.

(3. In a of a irameg'driving axle said trai'ne and capable of a limited lateral movement relative thereto; forked levers mounted in pivot bearings rigid with said frame; rollers on said leversengaging said boxes; and spring elements engaged by said locomotive engine, the COlIllJllir. boxes mounted in levers, said spring elements being disposed so as to resist the movements of the lovers upon rotation thereof caused byrthe inward movement of said boxes.

T. In a locomotive engine, the combination of a frame; driving axle boxes mounted in aid frame and capable of vertical and lateral movement relative to said "frame; levers ol inverted V-shape mounted in. pivot bearsaid frame; rollers on the boxes and capable of vertical movement relative thereto; and spring elements engaged by the closed end ot the V, said spring elements being disposed so as to resist the movement of the closed ends of the levers upon rotation o;t such levers caused by the inward movement of said boxes.
